Have a 7.62 upper from you guys like 6 years ago. Very accurate, and extremely reliable too. Enhanced firing pin. Never any problems.. Ever. Prolly lil over 12k rounds. Love it. Barely still in good shape/headspace and throat, rifling all good and only steel case has been through it.
@@shitcreekwarrior8794 In my experience the new duramags from c products are the very best and second place being the older c products. i especially like their 28 rounders. Only 2 less rounds but MUCH less sticking out below rifle. joebob outfitters has em in 30s 28s and 15s i think.
You should mention, for those who are not familiar with this subject, that the reason for the increasing curve of the magazine is due to the taper of the cartridge case itself. With the 7.62 round having more taper than the 5.56 round.
Got the enhanced firing pin AND heavy hammer spring from Black Rifle Arms for $25. Just did it up front to avoid any ignition issues. First 100 rounds were flawless
Bear Creek is one of my favorite companies. Every upper I have bought has worked perfectly, albeit on the 7.62x39mm it would not fire steel case hard primer ammo, but after I put a .003" longer enhanced firing pin and a stronger hammer spring, it is firing 7.62x39 flawlessly. As a matter of fact, it is now so reliable that it is my favorite ammo caliber. The point to this story is that at very low cost of about $25 for the enhanced firing pin and stronger hammer spring (which was kind of a challenge to put in) the Bear Creek 7.62x39 upper works flawlessly and fires any ammo (Tula, Wolf, other) that I put in it. Thanks BCA!
I just bought one of these. Can;t wait to get it! All three of my uppers are Bear Creek Arsenal. I love your products, and I love that they are affordably made in the USA
Bought an upper from you all 2 years ago . Maybe 2,000 rounds through it . Works flawlessly . This upper helps feed my family and puts deer and turkeys on the dinner table . Bought the upper after a friend had one and recommended it . Keep putting out great products .
Your 7.62X39, 1-in-8 twist, heavy barrel upper/barrel assembly has been a dream for me. I just went shooting with a friend who brought his precision Henry single-shot 30-30. The results were stunning. Once he was sighted in his 30-30, he would consistently hit 1" groups with open iron sights. He then picked up my "AR-47" (with a Sig Romeo red dot) and shot the same precision. A little bit of apples to oranges comparison, but also note that he was familiar with his Henry...he had never shot or even handled my AR-47 and I think that still says something about both the shootability and the precision of my BCA AR-47. Maranatha!
Love the upper. I've got the 16" side-charging handle 7.62x39 upper and I've only added an enhanced firing pin. Never had a single misfire, FTF, FTE, or any issue whatsoever out of about 500 rounds so far. The accuracy is also ridiculous and very competitive. The plug (in the place where the "wings" would be) is fantastic for keeping gas out of my face when I'm running my Dead Air suppressor. No joke this upper on my standard AR-15 lower (with enhanced firing pin) has reliability and accuracy that very well matches my Spike's Tactical Compressor ($3200 AR-15 with suppressor). I've only used Duramags with this upper and it's flawless. I am very impressed with this upper for the price. I don't even think about wanting to own an AK anymore. One note of improvement: the side charging screw. Comes loose quite easily. I red-loctited it in (semi-permanent) and it's never come loose since. I can't take out the BCG all the way, but can easily clean 90% of the inside of my AR-15 as is. 10/10 product and I'm proud to say I own this product from a company people would call "budget-brand". I call it quality with a humble price tag.
@@blakealvarez3199 High heat and love. Yea I originally used Blue loctite and it always came loose. Red works great. You have to carefully apply heat to it preferably with a heating tool that you can set the temperature for. You really do not need to remove it often. You can clean almost all of the upper without removing the BCG.
@@kearyginn1510 yes, it fits any standard AR15 lower. Also it requires AR mags that fit 7.62x39. AK mags will not fit. I highly recommend using duramag magazines chambered in 7.62x39. they come in 20 or 28 round versions and have never failed on me.
I love my 7.62 upper! But if you want it to run flawlessly you have to install and enhanced firing pin, a heavy hammer spring and use C products magazines. Then you can shoot any brand of Steel or brass.
Agree on the enhanced firing pin, and I only run C products mags,, ANY of the others are hit and miss ! but I have been running standard power hammer springs with no issues in two different 7.62x39 AR's
@@thedonfrom9019 I have found them online, either magwarehouse or primary arms, but others have them as well, sometimes hard to find 20 rounders , which I prefer,
@@steveeverett5261 thanks it’s been a hassle looking for these mags. I bought a 10.5 BCA 7.62 pistol and the gun store only had 30 rd pro mags . Which is malfunctioning. I kinda figured it was the problem
I have two uppers from you guys, love them both and they have functioned flawlessly with hundreds of rounds before I had to conserve ammo. Love USA made! Actually 4 uppers from BCA but two in 7.62x39
I bought one of your "COMEPLETE" rifles in 7.62x 39 an absolutely love it, it shoots 1" in groups with cheap steel cased ammo, wouldn't trade it for anything, but it is my dedicated "hoggin rifle". Just can't wait for the day when you get parts in to build the other uppers I want, an yes I know there hard to get right now. But I do check your E-mails daily for them, thx for the vid bro.
I built one up for my brother this past Christmas, he wanted something for home defense, bear and deer. He lives in the Appalachians and he loves it, ammo hasn't been too hard to find surprisingly.
I recently caved and bought your 16” 7.62x39 side charging upper. I threw on a VG6 Epsilon 7.62 that I had lying around and I am very happy with this upper receiver. Living in Maryland, 7.62 ammo is super easy to come by because AK style firearms are banned. So I’ve been walking into stores with empty shelves except for boxes upon boxes of 7.62x39. It’s certainly made this year a lot easier.
Stacked tolerances is the issue that most are having with the 7.62x39 In an AR-15. If you have a mil spec firing pin and a 3.5lb drop in trigger you will most likely start experiencing light primer strikes. The hammer spring in those are fine for US made brass case ammo for two reasons.The primers in US brass case ammo are set in flush and are softer, whereas the foreign made ammo has harder primers AND are set into the case significantly deeper requiring a longer firing pin throw and a slightly stronger hammer spring then comes with those sweet drop in triggers because of the limited space available in the outer assembly of the drop in triggers that make drop in triggers possible. These triggers were made for the 5.56 with the flush and softer primers for which they work flawlessly with. The AR-15 mags will not hold 30 rounds if you're doing that you are creating your own problems. The case of a 7.65x39 is not only a slightly larger diameter but it has a more severe taper to it. When the rounds are feeding in an AR mag all you will have touching is the bottom edge of the rimless case and leaving the bullet end of the cartridge flopping all over the place randomly. This may not be a big issue with 3 or 4 rounds but 30 creates a greater stacked tolerance and big problems feeding in some mags that are,...shall we say not quite mil spec. You can see this tolerance stacking issue clearly with your own eyes simply by laying out 30 rounds of 7.62x39 on your cleaning mat just like they would be stacked in your mag. Now stack them with the sides of the cases touching and you will see that an AK mag is shaped exactly to that curvature. If you're just fooling around you can get a few rounds in a standard 5.56 mag yes. Reliability will not be up to home defense or battle standards though. In other words, buy the correct mags if your life depends on it. Otherwise at the range just go have fun and experiment. That's after all how I learned this stuff too. 👍
Got 1 of these myself, highly recommend. BCA also has some of the best customer service in the industry, every time I call they handle any questions/issues promptly!
Love my bear creek arsenal 7.62 upper. I have a h3 buffer and standard carbine spring. I use a wolf extra power hammer spring for the trigger and an extended titanium firing pin. The rifle is super accurate and cycles beautifully and has no problem with cheap 7.62 ammo. My friends are always impressed. The asc 7.62 ar mags work perfect with it.
I purchased a 7.62 ar from yall and am impressed with it. Got the enhanced firing pin and no misfires. From my understanding, though, the curvature of the magazine is less so the diameter of the case and more the shape of the case. 7.62x39's case is slightly sloped as you go towards the bullet, which is why the curvature of the magazine is necessary (also why ak mags are curved). Obviously it will need to be longer due to the increased diameter though
I bought a 7.62x39 BCA upper about 5 years ago and it is a great piece of hardware. I threw a fairly cheap NCSTAR 1 - 8 power scope on it and it shoots perfect tight groups at 100 + yards. In fact... just about ALL of my uppers are from BCA. I even bought their AR10 complete 18" rifle a couple years ago and it is pretty nice. It had some feeding issues time to time but I haven't fed a ton of rounds through it. I think it just needs some more break in. Overall I am very impressed with BCA products. I bought my first upper from them chambered in 5.56 "BCA Brown Bear" and paired it with a New Frontier polymer complete lower receiver. I have since only went with aluminum lowers but the poly lower ran just fine. I use all sorts of mags but have become partial to the "Okay Industries" aluminum mags. They were at one time standard issue for military. They run great. Otherwise I use Hexmags and Pmags. I never did get a regular 5.56 mag to run my AR47 properly. Get the ASC aluminum 7.62 dedicated magazine for your 7.62 AR. You'll thank me. 😊
I have had the complete 7.62x39 platform for three years and have never had any issues with any type of ammo at all. I absolutely love that rifle. Recently purchased a suppressor for it so we’ll see how it does. I have no doubts.
Why don't you put enhanced firing pins in your uppers to begin with? Mine would fire wolf but would only fire Tula and Red Army Standard less than 50% of the time. I bought an enhanced pin and now it fires any brand.
@@Bear_Creek_Arsenal Just mail me the ammo, I'll test the sh#t out of it. 🤣 I bought one of your billet side charging pistol uppers a few months ago and could only find Tula....not impressed with reliability at all. I finally found some Wolf and it worked 100%. I don't keep firearms that are picky eaters so I spent $20 and boughr a enhanced pin and heavy spring. Tried the pin fix first and it has fired Tula, Wolf, Red Army Standard, Nosler, and Barnaul perfectly. Actually it works too good....I'm running low on ammo and prices and availability are even worse now. I use an Aero P lower with their standard trigger and it works fine. I have light strikes if I try the upper in other lowers with drop in or aftermarket competition FCGS. Not a big fan of mil spec triggers but it works.
@@Bear_Creek_Arsenal also, I was impressed with the quality of the upper. My only wish is that the handguard was shorter because I think I'm going to have to chop some of the end off or replace it when my suppressor I paid for months ago gets released.
I do agree. If a Enhanced Firing Pin seems to be an answer then yes I think they should be a part of the AR47 upper when purchased. I love mine. ASR mags I used seem to be a problem. Used C-mags and no issue. Any brass I had no issues other than feeding issues with the ASR's. I now do not have issues firing any steel jacket ammo. Maybe it's was mags? Or that I needed to put rounds out of the rifle to break in?? Either way I will look into purchasing a Enhanced Firing Pin to ensure it will fire as needed. But do think I shouldn't have to upgrade a complete upper so it will work as needed. My only complaint I have.
Mine runs steel with absolutely zero problems. No enhancement. Box stock Bear Creek Arsenal makes the best bang for your buck uppers out there. I own four and counting.
Bought a 16 inch side charge 7.62 in December for a AR build with a 80% lower. After research, installed the extra power spring on the trigger. After the build, ran 80 rounds of Tula through it. 61 fired, 19 did not. Light primer strikes. Installed the Black River Arms enhanced pin and proceeded to blast the 19 rounds and another 110 rounds of Tula. The spring did nothing, the enhanced pin did the trick. BCA should build them with the enhanced pin from the get go. Runs great now. Use ASC 30 round mags and have had 0 feed issues. Only other issue I had with the upper is that the barrel nut came loose near the end of the 110 round run as the M-loc and sight on it began to spin to the right. Took the upper apart and found that there weren't enough shims used to properly torque it while maintaining guardrail screw alignment. Contacted Bear Creek and they sent me 3 shims which I installed and the nut torqued properly with the screw holes lined up. Not impressed with the quality control, but pleased with the apology and the speedy shipment of shims. First class company. Liked my upper so much that I talked a friend into getting a .223 Wylde from BCA, although he got a rear charge. Thank you BCA.
I bought a 7.62 AR-15 complete upper from you guys 2 years ago and haven't had any malfunctions with it or major issues with it. I went with one of the cheaper varrents. Only issue I have is how much the barrel weighs. Makes my rifle very nose heavy. But that's not really your guys fault more less my fault for trying to save a lil bit of cash. You guys make solid products and I do recommend you guys to others for the prices you guys used to have. Prices now are a little to high now imo. As for steel cased ammo i have not had any problems with light strikes and i do not have the enhanced firing pin. I have ran into the magazine not seating if i filled them to capacity. Only way to get a full 30 round magazine to seat was to have the bcg all the way back and locked before puting the magazine in.
Best alternative to the paps and dracos which are now way overpriced. Can't wait to receive my next order of these. Great products and prices, keep it up!
@@dominiquedaughtrey6622 I just made sure I used a mil-spec trigger in my lower. I used a Schmit machine and tool trigger from Brownells. They are about $40 but worth it.
Purchased a 7.5" from BCA Aug 2021, using AR Stoner mags, PSA lower,, works great...good job with the new firing pin and extractor...I was skeptical, but it did not fail..great job BCA👍👍👍
It took 20 years to get my DPMS 7.62 upper to be reliable-most of the time: would only run fmj brass $$. SO: polished feed ramps, found a few mags that feed right, bolt broke; so new one and enhanced pin.....then no misfires; only blowback issues. Gas block swapped, was running cheap ammo fine until last weekend. Here we go again....
I just went to the range with my new BCA 7.62x39 billet 7.5 inch upper (rear charging) with PSA pistol lower, with added enhanced firing pin and ASC 30 rd mags and Tulammo rounds. I shot the first round, checked placement, cleaned the barrel and then adjusted the front sight , then fired 3 more rounds and sighting in at 25 yards my 2-4 shot (3 shot group) was nice and tight almost touching in a triangle. I am very happy with this upper from BCA. Very accurate even with cruddy cheap iron sights. I’ll be getting better iron sights soon. 🤠
I bought a x39 18" upper from a different company without the BCG & charging handle a year or so ago. I got a complete rifle lower from Joe Bob Outfitters which came with a ridiculously heavy trigger. Then I sourced a x39 BCG with an enhanced firing pin. The rifle came together under $400 not counting scope. It was very reliable but with that trigger no fun and I wasn't accurate. I went through a few lighter triggers, from 3 lbs to 4.5 lbs and different buffer weights. I ended up with a H-buffer and PSA EPT mil weight trigger. This is a great setup. I may not need the H buffer but it all came together reliably. I used both ASC and C-product 20 round magazines. I had one problem with the ASC mag where the follower jammed sideways. Never had a problem with the 20 round C-Product mags. I would call this an accurate setup, but I am only shooting clays and steel up to 100 yards. More accurate than my Zastava m70 AK but that is only running iron sights so not apples to apples. I'm using Tula, Red Army and Wolf. I have some Belom brass but am waiting until I have 100 yds and some paper to test it.
They drop them from time to time. I assume when sales slow. I purchased a upper 2 months ago for 289. Maybe not the 239-260$ they were before but then again they were always worth more then that.
The 7.62 and the 6.5 Grendel magazines are the exact same thing so you could use either one of those. And for my 7.62 AR pistol build it will not run Steelcase but it has absolutely zero problems running brass.
The enhanced firing pin isnt needed because of "harder" primers. The pin is needed because ammo like Tulammo set the primers deeper and you need the longer pin to reach deeper. I have had your 7.62x39 upper since 2016 and fired brass case, wolf and red army with no issue. Now when I fired tulammo without the EFP it received light primer strikes. Start offering the EFP with your uppers
A Wolff Extra Power Hammer Spring, An Enhanced Firing Pin And C-Products Magazines Are A Must For 7.62x39 AR-15's To Run Reliably! I've Been Running This Combination Successfully For 6 Year's! Thanks For The Video! ✌️🇺🇲✌️
i thought the 7.62 mags are curved more to accommodate the more severe taper of the round from the base to the bottleneck. the 556 is basically straight from the base to the bottleneck so the mags do not curve much. thanks for the video, i would love to have an 7.62x39 ar.
The 7.62 AR mags are curved more to accommodate the case taper of the 7.62. For a firearms manufacturer this guy gave a rather lousy description of the mags and the enhanced firing pin. BCA will not get my business. Reminds me of home garage AR builders.
I bought the 7.62x39 side charger gen 2.PSA Lower.I cleaned and lightly lubed.Installed enhanced firing pin.First charge using Duramag c product 30 rd mag steel case ammo misfire rd half in mag jammed.Dug it out.My feed problem solved with oiled feed ramp lightly.Running smooth now.
i have this upper and i love it, i also own a 10.5 556 works amazing! i have my neighbor building 2 16inch 556 uppers also. great price and great quality for the price! you guys rock
I always use these barrels and bcg’s for my 7.62x39 rifles. Always get the BRA enhanced firing pins and you’ll have no more light primer strikes and call it a day. Shoots sub MOA with Barnaul ammo and it wipes the floor with hogs when I pull this rifle out. Also just run the CPD mags. Everything else just isn’t worth wasting money on.
So far I've gotten 2- 5.56, 6.5 grendel and a .450 bushmaster uppers from you guys and they've all been great other then feed ramps was a little shallow on the 6.5 grendel. Would only run ball ammo, sanded down the feed ramps a bit and all is well. I'm now looking into the 7.62x39. All have been absolutely accurate. Cant beat the price for what ya get!! Keep up the solid work fellas.
If you compare a Russian mil spec 7.62x39 Berdan primer to a 5.56 Boxer primer (or just about any US made rifle cartridge primer) you will see that the 7.62x39 primer sits a little deeper below the surface of the rim. This is why a slightly longer firing pin tip helps set off the primer. It's actually debatable if the actual hardness of the Berdan primers is even a factor. If it truly was a factor, it would seem that a stronger hammer spring as well as an enhanced pin would be necessary.
I am of this belief. Before I got an advanced firing pin I could tell which rounds would get a light strike just by feeling how deep the primers were set with about a 90% accuracy. Since upgrading to the advanced firing pin I've only had one light strike and that primer was the deepest set I've ever seen. Still went bang on the 2nd try.
@@NismoXero I believe it. Since I made that post above, I have installed a trigger with a very light 2.5 lb hammer spring. With the longer firing pin, it still sets off Russian steel x39 ammo with no problems.
Purchased one a of these a couple of years back. Purchase a heavy hammer spring and a enhanced firing pin and was good to go. Haven't had any issues after well over 500 rounds of red army. Also ASC 20 round mags work flawlessly.
I had fte issues with my BCA side charger in 7.62x39. I traced it to a week extractor spring. I replaced the bolt with a NIB version from AIM Surplus, and it's good to go. I also use 28 round duramags. They're very high quality
Have 2 10.5 in 7.62 uppers one side charge one rear charge and both out of the box can only get it one shot off and the next one is a light primer strike. Added an enhanced firing pin and enhanced hammer spring and they both run flawlessly
Friend of mine just bought a bran new 7.62/39 upper first try he loaded it with that cheap steel cased rounds..and it wouldn't go all the way into the chamber..and the rifle would not fire, because the round wasn't all the way in..couldn't pull the charging handle and eject the round,,he had to brake the rifle down and tap the BCG with a piece if wood and a small hammer to get the round out of the chamber,,asked a gunsmith he said you can't use cheap Russian AK rounds in a Precision AR rifle,, its too tight of a tolerance,,its not a sloppy loose weapon like an AK..he said buy some American made brass rounds,,because the steel ones are coated with a lacquer so the casing doesn't rust..and that half a mill of coating , is just enough to jam up your rifle,,so he bought American brass rounds and it worked like a dream!!!
I ordered and installed the Advanced Firing Pin that you recommended in my message below. I went out and fired 120 rounds with no light primer strikes! Thanks for the suggestion... I would recommend that your company either make your own adv. firing pin for your or obtain them from someone else moving forward.
I think the curve on the 7.62x39 magazines is more to do with how the cartridge tapers, than it is with it's width/diameter. Just look at .308 Win mags, they aren't as curved as 7.62x39 mags. But very good info nonetheless.
My BCA 762 upper is my main rig at the moment and I love it. I'm using the cheapest steel case stuff I can find and had a ton of LPS with the stock pin, but I swapped it out for the enhanced pin and hammer spring and haven't had a problem since. C Product mags seem to feed the best for me, got some ASC's too and Duramag makes a half decent 762 AR mag too. Now if someone *cough cough* could make a slick nickel boron BCG for 762 *cough cough* that would be cool. :)
I believe a person should have a 7.62x39 upper on hand. Let's face it, most of the ammo people have today is either .223/5.56 or 7.62x39. You should have the option to fire either one.
After all the trouble I had with 762 mags, I said screw it. I went out and bought the 'multimag' instead. Rounds on the 762 dedicated would constantly jam coming out of the mag, round was catching on the front lip. Had to file the space wider on every mag I had. Saw a vid on the multimag and decided , yeah its a few bucks more but lets see what happens. Worked prefect, bought 4 more. Might only hold 28 rounds instead of 30, bit I think I can suffer through it. I still have my other repaired mags, they work perfectly now in my Grendel as well. As to the trigger spring, decided not to even mess with it, put an adjustable drop in instead. Zero issues. Firing pin? Bought a BCG with one already in it.
Are you referring to the UniMag from Ross Defense? If so, fantastic choice. The UniMag is the only magazine i use in my 7.62 AR. Works flawless with no modifications. And, i can use it in different AR platforms!
I just got one of the 16”, right side-charging 7.62x39 uppers from BCA. I’ve had some issues, which have been mostly resolved. Now I’m looking for the same in 10.5”…Out of Stock… waiting, waiting…
I use an enhanced firing pin in all my Ar’s they work great in 5.56/.223 /.300blk when shooting the doo doo steel cased. All my AR’s have drop in triggers like the rise 140/434’s which are known for LPS with brass case and worse with steel. I don’t get pierced primers or anything weird. They work and I don’t have change springs or modify the springs to get them to work 100% of the time. Im still looking for an enhanced FP for the .308 bcg.
When ammo became harder to get BCA had 7.62 x49 pistol and carbine compleat uppers available. They're awesome and both have performed without any major issues. They needed to break in a bit, but, after that they were fine. My next will be 12.7x42 carbine. For many reasons, but, not the least of which means all my 30 round magazines are now 10 round magazines ... right? 😉 addendum. Great product, great value, surprisingly fast delivery.
I've heard about their fast delivery, great products and certainly great value from researching. I ordered a complete upper on the 10th of Jan and it still hasn't shipped out, few days away from two weeks now. I ordered a stock and buffer tube kit the same day from a place called Moriarti Armaments and once I ordered it, they sent me an email conformation stating this "Due to unprecedented demand and enhanced safety protocols, please allow 4-6 weeks for your order to process and ship" so with hearing about BCA having fast delivery I thought to myself, I'm gonna have all the stuff I need and be without a stock and buffer tube assembly, so I ordered another one from a place that sent me some parts I ordered a couple days after I ordered and that showed up, but guess what, that stock and buffer tube kit from Moriarti Armaments came today Jan 21st. Haha well I guess I have some stocks and buffer tube kits for future builds.
I just purchased a bear creek 16inch left side charging 7.62 ar upper. I installed the enhanced firing pin plus a binary trigger. The upper receiver hasn't jammed once. Close to 800 rounds. Side charging handle is a little jankey but overall a great upper receiver very happy with it!
MY KS47 gen2 already came with enhanced pin and stronger spring. It has a single feed ramp too to help with feeding. It eats whatever I feed it. The biggest issue with the AR47's now is making sure you have a BCG that will last at least 5000 rounds. It also accepts AK mags.
Just purchased the Gen 2 side charging upper 16" in 762x39. I really look forward to putting this upper on and shooting it. Something a friend of mine has said is you'll want to get a heavier buffer (H3 around 5oz, Odin Works makes a great adjustable weight buffer but you can buy a standard H3) to help with cycling.
Hey Michael, enjoy your new upper! We recommend a standard weight or H1 buffer for 7.62x39. A heavy buffer will help with felt recoil, but can cause cycling issues if it's too heavy
You can fix firing pin with drill press. Insert small side in chuck set 1k RPM. use hand file on shoulder take off .020 - .025 or look for .045 to .050 pin protrusion from bolt face.
Love you're guys product built 6 ar with you're parts because you guys had good reliable parts at the average working man's price but prices keep skyrocketing gotta be better then the rest of them using current situation to make more money
I’ve got a 16 inch in 7.62 by BCA and I JUST bought a 10.5 inch barrel last night. I’ve also got a 5.56 BCA 10.5 pistol build and a 20 inch barrel in 5.56. I’ll be swapping the barrels out and I’ll be able to enjoy all 4 rifles (not at the same time as I only have 2 BCGs, but multiple bolts for both). I’ll swap out barrels accordingly to how I feel that day before the range. It’s gonna be fun! PLEASE PUT MORE SIDE CHARGING BCGs ON THE SITE SO I CAN HAVE AT LEAST 1 SPARE.
The main issue I have found is magazines. I have a few that allowed the rear lip on the cartridge to trip the bolt catch. So I just adjusted the bolt catch. Had an ASC mag that had feed issues, Swapped the mag spring out with a slightly shortened AK mag spring.
I bought the BCA upper with bcg combo and the BCA 14.5 inch barrel about 2 years ago. Built it on a PSA stripped lower with KAK lower parts kit. Never had a failure to feed or a misfire! Don't know if it has an enhanced firing pin. Used C products and ASC mags. All working good after 1200 rounds.....sadly I can't go shooting as much as I like!
ASC mags are terrible. Everyone I have heard from has switched to c products but personally I managed to find a company that was going out of business in Texas called Ross Defense Systems that makes a Uni-Mag which will run 25 rounds for 7.62x39. Bought two mags, loved them so much and they worked so well I bought five more the day after I first used them and have been a believer since. Have run thousands of rounds through the Uni-Mags and never once had a FTF. With ASC I have had about a 10-30% FTF rate per mag. Cannot speak to c products personally but everyone says they're great. Edit: as a note the only reason I dont have the c products stuff is it was all out of stock when i got my upper and my only option was to find another mag that would work.
I buy from y'all all the time, all but one of my AR's have your barrel so i was gonna let you know if you want a light trigger and always fire a 762x39 go with hiper fire , I think it's the EDMT trigger, about $89 and it works amazingly !!!!just trying to help....love you guys

I like your uppers. I prefer the side charging to the rear charging, it's just more comfortable for me. There is nothing wrong with rear charging I just prefer the side charging. I would like to see this use a piston system however. That being said... You are incorrect about the mags. The reason the 5.56 mags malfunction with 762 is called stacked tollorances. It's not the dia. of the round. If it was the dia. of the round then 300 bk would have feed issues also. The reason 7.62x39 fails to feed is because of the tapered case. If you stack 2 or 3 it's not real bad but if you stack 30 its 30x the problem. If you want this illustrated you can dump out a box of 5.56 on the table and a box of 762 and stack them side by side. You will immediatly see the 762 start to take the shape of an AK mag. and the 5.56 take the shape of an AR mag. if you put 762 in an AR mag shape you will see only the bottom of the rounds will contact each other. This configuration in an AR mag is unstable as the rounds begin to lock together and the bullet end of the round trys to go flat against the next round and creates terrible misalignment in the mag. The reason a few rounds still work in the AR mag is that the stacked tollerances are minimal and the spring tension is also light and not pushing so hard against the rounds as to force the misalignment. Sorry for the long post but I'm not sure how to make it shorter...I hope that helps clarify the issue though.
Have a 7.62 upper from you guys like 6 years ago. Very accurate, and extremely reliable too. Enhanced firing pin. Never any problems.. Ever. Prolly lil over 12k rounds. Love it. Barely still in good shape/headspace and throat, rifling all good and only steel case has been through it.
what buffer/ spring and trigger?
What lower did you use?
What mags do you guys favor for 7.62 ARs
@@shitcreekwarrior8794 Duramag SS
@@shitcreekwarrior8794 In my experience the new duramags from c products are the very best and second place being the older c products. i especially like their 28 rounders. Only 2 less rounds but MUCH less sticking out below rifle. joebob outfitters has em in 30s 28s and 15s i think.
You should mention, for those who are not familiar with this subject, that the reason for the increasing curve of the magazine is due to the taper of the cartridge case itself. With the 7.62 round having more taper than the 5.56 round.
All I did was get a stiffer trigger spring and I’ve had no problem with steel case ammo. Bear creek baby. Carolinas Finest.
Psa pretty damn good too in carolina as well.
Got the enhanced firing pin AND heavy hammer spring from Black Rifle Arms for $25. Just did it up front to avoid any ignition issues. First 100 rounds were flawless
Bear Creek is one of my favorite companies. Every upper I have bought has worked perfectly, albeit on the 7.62x39mm it would not fire steel case hard primer ammo, but after I put a .003" longer enhanced firing pin and a stronger hammer spring, it is firing 7.62x39 flawlessly. As a matter of fact, it is now so reliable that it is my favorite ammo caliber. The point to this story is that at very low cost of about $25 for the enhanced firing pin and stronger hammer spring (which was kind of a challenge to put in) the Bear Creek 7.62x39 upper works flawlessly and fires any ammo (Tula, Wolf, other) that I put in it. Thanks BCA!
I just bought one of these. Can;t wait to get it! All three of my uppers are Bear Creek Arsenal. I love your products, and I love that they are affordably made in the USA
Run crap steel case with the enhanced firing pin out of my AR pistol. I LOVE this thing
Purchased a rear charging 762x39 BCA upper about a year and a half ago. Runs like a champ and 762x39 ammo is relatively plentiful and cheap.
Bought an upper from you all 2 years ago . Maybe 2,000 rounds through it . Works flawlessly . This upper helps feed my family and puts deer and turkeys on the dinner table . Bought the upper after a friend had one and recommended it . Keep putting out great products .
Your 7.62X39, 1-in-8 twist, heavy barrel upper/barrel assembly has been a dream for me. I just went shooting with a friend who brought his precision Henry single-shot 30-30. The results were stunning. Once he was sighted in his 30-30, he would consistently hit 1" groups with open iron sights. He then picked up my "AR-47" (with a Sig Romeo red dot) and shot the same precision. A little bit of apples to oranges comparison, but also note that he was familiar with his Henry...he had never shot or even handled my AR-47 and I think that still says something about both the shootability and the precision of my BCA AR-47. Maranatha!
Love the upper. I've got the 16" side-charging handle 7.62x39 upper and I've only added an enhanced firing pin. Never had a single misfire, FTF, FTE, or any issue whatsoever out of about 500 rounds so far. The accuracy is also ridiculous and very competitive. The plug (in the place where the "wings" would be) is fantastic for keeping gas out of my face when I'm running my Dead Air suppressor. No joke this upper on my standard AR-15 lower (with enhanced firing pin) has reliability and accuracy that very well matches my Spike's Tactical Compressor ($3200 AR-15 with suppressor). I've only used Duramags with this upper and it's flawless.
I am very impressed with this upper for the price. I don't even think about wanting to own an AK anymore. One note of improvement: the side charging screw. Comes loose quite easily. I red-loctited it in (semi-permanent) and it's never come loose since. I can't take out the BCG all the way, but can easily clean 90% of the inside of my AR-15 as is. 10/10 product and I'm proud to say I own this product from a company people would call "budget-brand". I call it quality with a humble price tag.
How will you remove the charging handle? Blue loctite keeps coming loose on me so I’ve been considering using red loctite.
@@blakealvarez3199 High heat and love. Yea I originally used Blue loctite and it always came loose. Red works great. You have to carefully apply heat to it preferably with a heating tool that you can set the temperature for. You really do not need to remove it often. You can clean almost all of the upper without removing the BCG.
So a BCA 7.62 upper fits a standard AR15 lower? Anderson lower
@@kearyginn1510 yes, it fits any standard AR15 lower. Also it requires AR mags that fit 7.62x39. AK mags will not fit. I highly recommend using duramag magazines chambered in 7.62x39. they come in 20 or 28 round versions and have never failed on me.
@@farmersneed THANK YOU VERY MUCH SIR!!
Ik its an old video, but id just like to say that i bought a 7.62x39 complete upper and love it! No issues at all.
Been using 20 rounds of 7.62 in metal 30 round 5.56 mags for years without issues.
That is the endorsement I was looking for.
Same
I love my 7.62 upper! But if you want it to run flawlessly you have to install and enhanced firing pin, a heavy hammer spring and use C products magazines. Then you can shoot any brand of Steel or brass.
The newer ones which I bought was a Gen 2 has the enhanced firing pin and a better charging handle.
Agree on the enhanced firing pin, and I only run C products mags,, ANY of the others are hit and miss ! but I have been running standard power hammer springs with no issues in two different 7.62x39 AR's
@@steveeverett5261 where do you find your c product mags?

I have found them online, either magwarehouse or primary arms, but others have them as well, sometimes hard to find 20 rounders , which I prefer,
@@steveeverett5261 thanks it’s been a hassle looking for these mags. I bought a 10.5 BCA 7.62 pistol and the gun store only had 30 rd pro mags . Which is malfunctioning. I kinda figured it was the problem

I have two uppers from you guys, love them both and they have functioned flawlessly with hundreds of rounds before I had to conserve ammo. Love USA made! Actually 4 uppers from BCA but two in 7.62x39
I love mine a lot. Use it to hunt hogs and never failed me (knocked on wood). Very accurate getting 1.2moa at 100yds using steel case ammo 154gr Tula.
Love mine! Over 3000rds, 3 Deers and still going strong! Thx BCA!
Hey you found a loophole! So in Commiefornia I'll just tell them "no this isn't a 30 round 5.56 magazine it's a 10 round 7.62 magazine"
😂
You can probably get away with that if you have a .450 or .50.
I bought one of your "COMEPLETE" rifles in 7.62x 39 an absolutely love it, it shoots 1" in groups with cheap steel cased ammo, wouldn't trade it for anything, but it is my dedicated "hoggin rifle". Just can't wait for the day when you get parts in to build the other uppers I want, an yes I know there hard to get right now. But I do check your E-mails daily for them, thx for the vid bro.
Thanks, I have owned your AR47 top for a couple years now and have no complaints to date.
I built one up for my brother this past Christmas, he wanted something for home defense, bear and deer. He lives in the Appalachians and he loves it, ammo hasn't been too hard to find surprisingly.
It's russian ammo on American soil.
I recently caved and bought your 16” 7.62x39 side charging upper. I threw on a VG6 Epsilon 7.62 that I had lying around and I am very happy with this upper receiver. Living in Maryland, 7.62 ammo is super easy to come by because AK style firearms are banned. So I’ve been walking into stores with empty shelves except for boxes upon boxes of 7.62x39. It’s certainly made this year a lot easier.
Stacked tolerances is the issue that most are having with the 7.62x39 In an AR-15. If you have a mil spec firing pin and a 3.5lb drop in trigger you will most likely start experiencing light primer strikes. The hammer spring in those are fine for US made brass case ammo for two reasons.The primers in US brass case ammo are set in flush and are softer, whereas the foreign made ammo has harder primers AND are set into the case significantly deeper requiring a longer firing pin throw and a slightly stronger hammer spring then comes with those sweet drop in triggers because of the limited space available in the outer assembly of the drop in triggers that make drop in triggers possible. These triggers were made for the 5.56 with the flush and softer primers for which they work flawlessly with. The AR-15 mags will not hold 30 rounds if you're doing that you are creating your own problems. The case of a 7.65x39 is not only a slightly larger diameter but it has a more severe taper to it. When the rounds are feeding in an AR mag all you will have touching is the bottom edge of the rimless case and leaving the bullet end of the cartridge flopping all over the place randomly. This may not be a big issue with 3 or 4 rounds but 30 creates a greater stacked tolerance and big problems feeding in some mags that are,...shall we say not quite mil spec. You can see this tolerance stacking issue clearly with your own eyes simply by laying out 30 rounds of 7.62x39 on your cleaning mat just like they would be stacked in your mag. Now stack them with the sides of the cases touching and you will see that an AK mag is shaped exactly to that curvature. If you're just fooling around you can get a few rounds in a standard 5.56 mag yes. Reliability will not be up to home defense or battle standards though. In other words, buy the correct mags if your life depends on it. Otherwise at the range just go have fun and experiment. That's after all how I learned this stuff too. 👍
I've heard with 7.62×39 kak bcg's are pretty good..
Got 1 of these myself, highly recommend. BCA also has some of the best customer service in the industry, every time I call they handle any questions/issues promptly!
Love my bear creek arsenal 7.62 upper. I have a h3 buffer and standard carbine spring. I use a wolf extra power hammer spring for the trigger and an extended titanium firing pin. The rifle is super accurate and cycles beautifully and has no problem with cheap 7.62 ammo. My friends are always impressed. The asc 7.62 ar mags work perfect with it.
I have this 7.62 upper, it functioned flawlessly right out of the box!! Ate steel-cased ammo like a champ
I purchased a 7.62 ar from yall and am impressed with it. Got the enhanced firing pin and no misfires. From my understanding, though, the curvature of the magazine is less so the diameter of the case and more the shape of the case. 7.62x39's case is slightly sloped as you go towards the bullet, which is why the curvature of the magazine is necessary (also why ak mags are curved). Obviously it will need to be longer due to the increased diameter though
I bought a 7.62x39 BCA upper about 5 years ago and it is a great piece of hardware. I threw a fairly cheap NCSTAR 1 - 8 power scope on it and it shoots perfect tight groups at 100 + yards. In fact... just about ALL of my uppers are from BCA. I even bought their AR10 complete 18" rifle a couple years ago and it is pretty nice. It had some feeding issues time to time but I haven't fed a ton of rounds through it. I think it just needs some more break in. Overall I am very impressed with BCA products. I bought my first upper from them chambered in 5.56 "BCA Brown Bear" and paired it with a New Frontier polymer complete lower receiver. I have since only went with aluminum lowers but the poly lower ran just fine. I use all sorts of mags but have become partial to the "Okay Industries" aluminum mags. They were at one time standard issue for military. They run great. Otherwise I use Hexmags and Pmags. I never did get a regular 5.56 mag to run my AR47 properly. Get the ASC aluminum 7.62 dedicated magazine for your 7.62 AR. You'll thank me. 😊
I just picked 1 up from y'all. Picked up the enhanced firing pin too. Haven't got to test em out yet, but it looks & feels great! I can't wait!
I have had the complete 7.62x39 platform for three years and have never had any issues with any type of ammo at all. I absolutely love that rifle. Recently purchased a suppressor for it so we’ll see how it does. I have no doubts.
Does the 7.62 take the same lower as a 5.56?
@@Mr_Originality yes sir. Special magazines but the lower is standard
I've had mine for about 2 years. Not one issue!!
Why don't you put enhanced firing pins in your uppers to begin with? Mine would fire wolf but would only fire Tula and Red Army Standard less than 50% of the time. I bought an enhanced pin and now it fires any brand.
Hi Cleetis, that is something we are considering, but want to test thoroughly before implementing
@@Bear_Creek_Arsenal Just mail me the ammo, I'll test the sh#t out of it. 🤣
I bought one of your billet side charging pistol uppers a few months ago and could only find Tula....not impressed with reliability at all. I finally found some Wolf and it worked 100%. I don't keep firearms that are picky eaters so I spent $20 and boughr a enhanced pin and heavy spring. Tried the pin fix first and it has fired Tula, Wolf, Red Army Standard, Nosler, and Barnaul perfectly. Actually it works too good....I'm running low on ammo and prices and availability are even worse now. I use an Aero P lower with their standard trigger and it works fine. I have light strikes if I try the upper in other lowers with drop in or aftermarket competition FCGS. Not a big fan of mil spec triggers but it works.
@@Bear_Creek_Arsenal also, I was impressed with the quality of the upper. My only wish is that the handguard was shorter because I think I'm going to have to chop some of the end off or replace it when my suppressor I paid for months ago gets released.
Mine won't fire Wolf. Only Tul or Red Army. Lol
I do agree. If a Enhanced Firing Pin seems to be an answer then yes I think they should be a part of the AR47 upper when purchased. I love mine. ASR mags I used seem to be a problem. Used C-mags and no issue. Any brass I had no issues other than feeding issues with the ASR's. I now do not have issues firing any steel jacket ammo. Maybe it's was mags? Or that I needed to put rounds out of the rifle to break in?? Either way I will look into purchasing a Enhanced Firing Pin to ensure it will fire as needed. But do think I shouldn't have to upgrade a complete upper so it will work as needed. My only complaint I have.
Thanks for the content. I have POF 7.62X39. Geissele Trigger. C product magazine. Works flawlessly, suppressed and unsuppressed. Very happy!!!
Mine runs steel with absolutely zero problems. No enhancement. Box stock Bear Creek Arsenal makes the best bang for your buck uppers out there. I own four and counting.
Bought a 16 inch side charge 7.62 in December for a AR build with a 80% lower. After research, installed the extra power spring on the trigger. After the build, ran 80 rounds of Tula through it. 61 fired, 19 did not. Light primer strikes. Installed the Black River Arms enhanced pin and proceeded to blast the 19 rounds and another 110 rounds of Tula. The spring did nothing, the enhanced pin did the trick. BCA should build them with the enhanced pin from the get go. Runs great now. Use ASC 30 round mags and have had 0 feed issues. Only other issue I had with the upper is that the barrel nut came loose near the end of the 110 round run as the M-loc and sight on it began to spin to the right. Took the upper apart and found that there weren't enough shims used to properly torque it while maintaining guardrail screw alignment. Contacted Bear Creek and they sent me 3 shims which I installed and the nut torqued properly with the screw holes lined up. Not impressed with the quality control, but pleased with the apology and the speedy shipment of shims. First class company. Liked my upper so much that I talked a friend into getting a .223 Wylde from BCA, although he got a rear charge. Thank you BCA.
The enhanced firing pin would be a great upgrade. Looking forward to this.💯
Hoping to implement it in the future!
And a heavier hammer spring!
I bought a 7.62 AR-15 complete upper from you guys 2 years ago and haven't had any malfunctions with it or major issues with it. I went with one of the cheaper varrents. Only issue I have is how much the barrel weighs. Makes my rifle very nose heavy. But that's not really your guys fault more less my fault for trying to save a lil bit of cash. You guys make solid products and I do recommend you guys to others for the prices you guys used to have. Prices now are a little to high now imo. As for steel cased ammo i have not had any problems with light strikes and i do not have the enhanced firing pin. I have ran into the magazine not seating if i filled them to capacity. Only way to get a full 30 round magazine to seat was to have the bcg all the way back and locked before puting the magazine in.
Best alternative to the paps and dracos which are now way overpriced. Can't wait to receive my next order of these. Great products and prices, keep it up!
seriously dont know why im only now seeing this in my feed, but awesome video.. i love my ar47!
The old just the tip argument !!!! Been using that since high school ...it works about 50\50
This is my favorite upper and use it to hunt hogs and deer. It's very accurate withTula soft points, and have had no issues with the stock firing pin.
I had issues with my stock firing pin but it was from KAK not bear creek
I had issues with my bca pin, I just took a little off the pin stop, and now it's 100 percent reliable, I'm using the mil spec hammer spring.
Howd you build this AR out
@@dominiquedaughtrey6622 I just made sure I used a mil-spec trigger in my lower. I used a Schmit machine and tool trigger from Brownells. They are about $40 but worth it.
That 154gr SP from Tula is no joke!
Love you guys at Bear Creek Arsenal, a MK18 style AR in 7.62×39 sounds amazing and hard hitting too.
Purchased a 7.5" from BCA Aug 2021, using AR Stoner mags, PSA lower,, works great...good job with the new firing pin and extractor...I was skeptical, but it did not fail..great job BCA👍👍👍
Just finished building one and love it. Ran 100 rounds through it on Sunday and not one issue. AR-47 is bad-@ss
It took 20 years to get my DPMS 7.62 upper to be reliable-most of the time: would only run fmj brass $$. SO: polished feed ramps, found a few mags that feed right, bolt broke; so new one and enhanced pin.....then no misfires; only blowback issues. Gas block swapped, was running cheap ammo fine until last weekend. Here we go again....
I just went to the range with my new BCA 7.62x39 billet 7.5 inch upper (rear charging) with PSA pistol lower, with added enhanced firing pin and ASC 30 rd mags and Tulammo rounds. I shot the first round, checked placement, cleaned the barrel and then adjusted the front sight , then fired 3 more rounds and sighting in at 25 yards my 2-4 shot (3 shot group) was nice and tight almost touching in a triangle. I am very happy with this upper from BCA. Very accurate even with cruddy cheap iron sights. I’ll be getting better iron sights soon. 🤠
Great to hear!
I bought a x39 18" upper from a different company without the BCG & charging handle a year or so ago. I got a complete rifle lower from Joe Bob Outfitters which came with a ridiculously heavy trigger. Then I sourced a x39 BCG with an enhanced firing pin. The rifle came together under $400 not counting scope. It was very reliable but with that trigger no fun and I wasn't accurate.
I went through a few lighter triggers, from 3 lbs to 4.5 lbs and different buffer weights. I ended up with a H-buffer and PSA EPT mil weight trigger. This is a great setup. I may not need the H buffer but it all came together reliably. I used both ASC and C-product 20 round magazines. I had one problem with the ASC mag where the follower jammed sideways. Never had a problem with the 20 round C-Product mags.
I would call this an accurate setup, but I am only shooting clays and steel up to 100 yards. More accurate than my Zastava m70 AK but that is only running iron sights so not apples to apples. I'm using Tula, Red Army and Wolf. I have some Belom brass but am waiting until I have 100 yds and some paper to test it.
A little disappointed about the price jump on the uppers😳
Right, might as well get a PSA
If you watch 704 tac review of this upper it was a sub 200$ upper
Thank Beijing Biden's White House installation for the price jump
@@sykoslim8851 it's no joe bro the jump happened way before joe!
They drop them from time to time. I assume when sales slow. I purchased a upper 2 months ago for 289. Maybe not the 239-260$ they were before but then again they were always worth more then that.
The 7.62 and the 6.5 Grendel magazines are the exact same thing so you could use either one of those. And for my 7.62 AR pistol build it will not run Steelcase but it has absolutely zero problems running brass.
The enhanced firing pin isnt needed because of "harder" primers. The pin is needed because ammo like Tulammo set the primers deeper and you need the longer pin to reach deeper. I have had your 7.62x39 upper since 2016 and fired brass case, wolf and red army with no issue. Now when I fired tulammo without the EFP it received light primer strikes. Start offering the EFP with your uppers
It’s a $300 upper...
An EFP is $8. Not hard to make standard in their BCG

i thought the 7.62 mags are curved more to accommodate the more severe taper of the round from the base to the bottleneck. the 556 is basically straight from the base to the bottleneck so the mags do not curve much. thanks for the video, i would love to have an 7.62x39 ar.
Get one! The are soooo worth it.
The 7.62 AR mags are curved more to accommodate the case taper of the 7.62. For a firearms manufacturer this guy gave a rather lousy description of the mags and the enhanced firing pin. BCA will not get my business. Reminds me of home garage AR builders.
John - you are correct.

@@Bear_Creek_Arsenal definitely loyal
I always use these barrels and bcg’s for my 7.62x39 rifles. Always get the BRA enhanced firing pins and you’ll have no more light primer strikes and call it a day. Shoots sub MOA with Barnaul ammo and it wipes the floor with hogs when I pull this rifle out. Also just run the CPD mags. Everything else just isn’t worth wasting money on.
So far I've gotten 2- 5.56, 6.5 grendel and a .450 bushmaster uppers from you guys and they've all been great other then feed ramps was a little shallow on the 6.5 grendel. Would only run ball ammo, sanded down the feed ramps a bit and all is well. I'm now looking into the 7.62x39. All have been absolutely accurate. Cant beat the price for what ya get!! Keep up the solid work fellas.
Thanks for answering the important questions that are on everyone's mind, much appreciated.
Just got mine in the mail yesterday!
If you compare a Russian mil spec 7.62x39 Berdan primer to a 5.56 Boxer primer (or just about any US made rifle cartridge primer) you will see that the 7.62x39 primer sits a little deeper below the surface of the rim. This is why a slightly longer firing pin tip helps set off the primer. It's actually debatable if the actual hardness of the Berdan primers is even a factor. If it truly was a factor, it would seem that a stronger hammer spring as well as an enhanced pin would be necessary.
I am of this belief. Before I got an advanced firing pin I could tell which rounds would get a light strike just by feeling how deep the primers were set with about a 90% accuracy.
Since upgrading to the advanced firing pin I've only had one light strike and that primer was the deepest set I've ever seen. Still went bang on the 2nd try.
@@NismoXero I believe it.
Since I made that post above, I have installed a trigger with a very light 2.5 lb hammer spring. With the longer firing pin, it still sets off Russian steel x39 ammo with no problems.
Purchased one a of these a couple of years back. Purchase a heavy hammer spring and a enhanced firing pin and was good to go. Haven't had any issues after well over 500 rounds of red army. Also ASC 20 round mags work flawlessly.
As I just mentioned in a testing video y'all should just include the enhanced pin ..it would only increase your good reputation!!
Thank You man, I absolutely love educational videos like this. We need way more! New Sub!

You're welcome!
Friend of mine just bought a bran new 7.62/39 upper first try he loaded it with that cheap steel cased rounds..and it wouldn't go all the way into the chamber..and the rifle would not fire, because the round wasn't all the way in..couldn't pull the charging handle and eject the round,,he had to brake the rifle down and tap the BCG with a piece if wood and a small hammer to get the round out of the chamber,,asked a gunsmith he said you can't use cheap Russian AK rounds in a Precision AR rifle,, its too tight of a tolerance,,its not a sloppy loose weapon like an AK..he said buy some American made brass rounds,,because the steel ones are coated with a lacquer so the casing doesn't rust..and that half a mill of coating , is just enough to jam up your rifle,,so he bought American brass rounds and it worked like a dream!!!
I ordered and installed the Advanced Firing Pin that you recommended in my message below. I went out and fired 120 rounds with no light primer strikes! Thanks for the suggestion... I would recommend that your company either make your own adv. firing pin for your or obtain them from someone else moving forward.
Hey Reade, good to hear! That is something we're testing/considering
I think the curve on the 7.62x39 magazines is more to do with how the cartridge tapers, than it is with it's width/diameter. Just look at .308 Win mags, they aren't as curved as 7.62x39 mags. But very good info nonetheless.
My BCA 762 upper is my main rig at the moment and I love it. I'm using the cheapest steel case stuff I can find and had a ton of LPS with the stock pin, but I swapped it out for the enhanced pin and hammer spring and haven't had a problem since. C Product mags seem to feed the best for me, got some ASC's too and Duramag makes a half decent 762 AR mag too.
Now if someone *cough cough* could make a slick nickel boron BCG for 762 *cough cough* that would be cool. :)
There's companies with aftermarket bcg
I believe a person should have a 7.62x39 upper on hand. Let's face it, most of the ammo people have today is either .223/5.56 or 7.62x39. You should have the option to fire either one.
Brown Bear works the best in western block guns. No problems in my Mini-30.

Make sure you have an extra extractor. Mine broke after 100 rounds
After all the trouble I had with 762 mags, I said screw it. I went out and bought the 'multimag' instead.
Rounds on the 762 dedicated would constantly jam coming out of the mag, round was catching on the front lip. Had to file the space wider on every mag I had.
Saw a vid on the multimag and decided , yeah its a few bucks more but lets see what happens. Worked prefect, bought 4 more. Might only hold 28 rounds instead of 30, bit I think I can suffer through it.
I still have my other repaired mags, they work perfectly now in my Grendel as well.
As to the trigger spring, decided not to even mess with it, put an adjustable drop in instead. Zero issues.
Firing pin? Bought a BCG with one already in it.
Are you referring to the UniMag from Ross Defense? If so, fantastic choice. The UniMag is the only magazine i use in my 7.62 AR. Works flawless with no modifications. And, i can use it in different AR platforms!
I just got one of the 16”, right side-charging 7.62x39 uppers from BCA. I’ve had some issues, which have been mostly resolved. Now I’m looking for the same in 10.5”…Out of Stock… waiting, waiting…
I use an enhanced firing pin in all my Ar’s they work great in 5.56/.223 /.300blk when shooting the doo doo steel cased. All my AR’s have drop in triggers like the rise 140/434’s which are known for LPS with brass case and worse with steel. I don’t get pierced primers or anything weird. They work and I don’t have change springs or modify the springs to get them to work 100% of the time. Im still looking for an enhanced FP for the .308 bcg.
When ammo became harder to get BCA had 7.62 x49 pistol and carbine compleat uppers available. They're awesome and both have performed without any major issues. They needed to break in a bit, but, after that they were fine. My next will be 12.7x42 carbine. For many reasons, but, not the least of which means all my 30 round magazines are now 10 round magazines ... right? 😉 addendum. Great product, great value, surprisingly fast delivery.
I've heard about their fast delivery, great products and certainly great value from researching. I ordered a complete upper on the 10th of Jan and it still hasn't shipped out, few days away from two weeks now. I ordered a stock and buffer tube kit the same day from a place called Moriarti Armaments and once I ordered it, they sent me an email conformation stating this "Due to unprecedented demand and enhanced safety protocols, please allow 4-6 weeks for your order to process and ship" so with hearing about BCA having fast delivery I thought to myself, I'm gonna have all the stuff I need and be without a stock and buffer tube assembly, so I ordered another one from a place that sent me some parts I ordered a couple days after I ordered and that showed up, but guess what, that stock and buffer tube kit from Moriarti Armaments came today Jan 21st. Haha well I guess I have some stocks and buffer tube kits for future builds.
@@ogbigbubbakush can't have too many "parts"
@@gdaddy5193 Yes, indeed haha I agree
I just purchased a bear creek 16inch left side charging 7.62 ar upper. I installed the enhanced firing pin plus a binary trigger. The upper receiver hasn't jammed once. Close to 800 rounds. Side charging handle is a little jankey but overall a great upper receiver very happy with it!
Did you install a franklin binary?
@@Whohoohoo fostech echo binary trigger. Ive put a couple thousand rounds of 7.62 x 39 is still tickin
c products mags are the best in my opinion.
Currently considering buying one of your 7.62 uppers. Thanks for all the great tips.👍🏻🍻
Won't find any 7.62 uppers cheaper or better than than most companies.
MY KS47 gen2 already came with enhanced pin and stronger spring. It has a single feed ramp too to help with feeding. It eats whatever I feed it. The biggest issue with the AR47's now is making sure you have a BCG that will last at least 5000 rounds. It also accepts AK mags.
get C mags
I’m using 10 and 20 round ASC mags and they work great.
Just purchased the Gen 2 side charging upper 16" in 762x39. I really look forward to putting this upper on and shooting it. Something a friend of mine has said is you'll want to get a heavier buffer (H3 around 5oz, Odin Works makes a great adjustable weight buffer but you can buy a standard H3) to help with cycling.
Hey Michael, enjoy your new upper! We recommend a standard weight or H1 buffer for 7.62x39. A heavy buffer will help with felt recoil, but can cause cycling issues if it's too heavy
You can fix firing pin with drill press. Insert small side in chuck set 1k RPM. use hand file on shoulder take off .020 - .025 or look for .045 to .050 pin protrusion from bolt face.
Love you're guys product built 6 ar with you're parts because you guys had good reliable parts at the average working man's price but prices keep skyrocketing gotta be better then the rest of them using current situation to make more money
Raw material prices have risen dramatically. We're doing our best to keep prices as low as we can
I’ve got a 16 inch in 7.62 by BCA and I JUST bought a 10.5 inch barrel last night. I’ve also got a 5.56 BCA 10.5 pistol build and a 20 inch barrel in 5.56. I’ll be swapping the barrels out and I’ll be able to enjoy all 4 rifles (not at the same time as I only have 2 BCGs, but multiple bolts for both). I’ll swap out barrels accordingly to how I feel that day before the range. It’s gonna be fun!
PLEASE PUT MORE SIDE CHARGING BCGs ON THE SITE SO I CAN HAVE AT LEAST 1 SPARE.
Hey Namon, sounds like a great set up! Hoping to get some more side charging BCGs back in stock soon
Just ordered mine. Thanks for the info. Was waiting on ordering because I couldn’t find mags.
@Shane Wood use duramax they won't let you down 💯🇺🇸
The main issue I have found is magazines. I have a few that allowed the rear lip on the cartridge to trip the bolt catch. So I just adjusted the bolt catch. Had an ASC mag that had feed issues, Swapped the mag spring out with a slightly shortened AK mag spring.
I bought the BCA upper with bcg combo and the BCA 14.5 inch barrel about 2 years ago. Built it on a PSA stripped lower with KAK lower parts kit. Never had a failure to feed or a misfire! Don't know if it has an enhanced firing pin. Used C products and ASC mags. All working good after 1200 rounds.....sadly I can't go shooting as much as I like!
Are any of you having issues with asc mags like they suggest? They have been absolute crap for me. I switched to C products. No issues .
If you clean up the top of he ASC mags they work decently but c products is what I’ve found to be best in my research and what I’ve been told to get
ASC mags are terrible. Everyone I have heard from has switched to c products but personally I managed to find a company that was going out of business in Texas called Ross Defense Systems that makes a Uni-Mag which will run 25 rounds for 7.62x39. Bought two mags, loved them so much and they worked so well I bought five more the day after I first used them and have been a believer since. Have run thousands of rounds through the Uni-Mags and never once had a FTF. With ASC I have had about a 10-30% FTF rate per mag. Cannot speak to c products personally but everyone says they're great.
Edit: as a note the only reason I dont have the c products stuff is it was all out of stock when i got my upper and my only option was to find another mag that would work.
Just a suggestion, check out the UniMag by Ross Defense.
I've had nothing but trouble with the ASC 20 rnd mags in my BCA 7.62x39 upper, even after doing recommended modifications as seen on RUclips. Junk
I buy from y'all all the time, all but one of my AR's have your barrel so i was gonna let you know if you want a light trigger and always fire a 762x39 go with hiper fire , I think it's the EDMT trigger, about $89 and it works amazingly !!!!just trying to help....love you guys
I got a 7.62x39 upper from you guys and the extractor blew apart on me at like 200 rounds
We are very sorry to hear that. Please submit a warranty request on our website and we will certainly assist in getting this rectified. Here is a video that will guide you through the warranty process: ruclips.net/video/eR2B27WtoZM/видео.html We look forward to getting you shooting again.
I like your uppers. I prefer the side charging to the rear charging, it's just more comfortable for me. There is nothing wrong with rear charging I just prefer the side charging. I would like to see this use a piston system however. That being said...
You are incorrect about the mags. The reason the 5.56 mags malfunction with 762 is called stacked tollorances. It's not the dia. of the round. If it was the dia. of the round then 300 bk would have feed issues also. The reason 7.62x39 fails to feed is because of the tapered case. If you stack 2 or 3 it's not real bad but if you stack 30 its 30x the problem. If you want this illustrated you can dump out a box of 5.56 on the table and a box of 762 and stack them side by side. You will immediatly see the 762 start to take the shape of an AK mag. and the 5.56 take the shape of an AR mag. if you put 762 in an AR mag shape you will see only the bottom of the rounds will contact each other. This configuration in an AR mag is unstable as the rounds begin to lock together and the bullet end of the round trys to go flat against the next round and creates terrible misalignment in the mag. The reason a few rounds still work in the AR mag is that the stacked tollerances are minimal and the spring tension is also light and not pushing so hard against the rounds as to force the misalignment. Sorry for the long post but I'm not sure how to make it shorter...I hope that helps clarify the issue though.
Diameter and the case is tapered on the 7.62 is the reason for the banana shaped mags for AK and such.
Good to know we can use a less than fully loaded standard mag
